## About

The three-way at the top of the second-generation 500 Series, and the only one in the range that separates midrange from bass: a 125 mm carbon cone of its own crossing at 220 Hz, above a pair of 165 mm carbon woofers. The 29 mm soft dome comes down from the Corinium, as it does throughout the series. All of it sits in a cabinet 1.05 m tall and 185 mm across — the same width as the AE509² beside it — standing on aluminium outriggers that reach well past the box.
